Application led April 21, 1914. Serial No. 833,371.`

To "all whom it may concern Be it known that we, ISAAC A. ALLEN, Jr., and CHARLES W. S'roNsnL, citizens of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Cord-Fasteners, of which the following is a specification.

This invention relates to cord-fasteners. The term cord is employed in a generic sense to cover not only cord itself but chain, strap, rope and analogous devices. While a cord-fastener comprising our invention can be utilized with advantage in widely-difer ent ways, it is of especial advantage when used for connecting cords, chains or straps such as are associated with windows, with the sashes and weights thereof.

There arevarious forms in which an article embodying our invention can assume;

one of these is shown in the drawings accompanying and forming part of the present specification. This particular embodiment will be fully set forth in the following description-primarily to enable skilled in the art to practise the invention. It will be clear that we do not restrict ourselves to this disclosure; we can depart therefrom in divers respects within Ithe scope of the invention defined by the claims following said description.

Among the objects of the invention are the provision of an article of the character described, which is simple in constructiong and which can be inexpenslvely and easily made, which can 'be quickly applied and which is rendered operative by a pull or strain on the cord or like part, by reason of which no extraneous means are requisite for this purpose, the hold of the fastener on the cord when said fastener is setbeing f so secure as to prevent practically the possicord being connected with the sash and with those 1 of the cord with the fastener. bility of their being accidentally separated.

Referring to said drawings: Figure 1 visl a sectional side elevation of portion of al window showing a part of the sash, a weight and intermediate guidepulley and oord, the

and being in set relation. Fig.v 3 is a side elevation of one of the fasteners. Fig. 4 is an elevation as seen from the right in Fig.

3, and, Fig. 5 is a bottom plan View of said fastener shown in each of these three views 1n open or unset condition. Figs. 6 and 7 areperspective views of the fastener in its original relation, the cord not appearing in Fig. 6 but being shown in Fig. 7 in looped connection with the fasteners. 8 is a perspective view of the fastener in set or active relation, thecord for sake of clearness 'being omitted. Fig. 9 is a fiat or developed View of a blank from which the fastener can be made.

Like characters refer to like throughout the several figures.

The fastener covered herein is along the same general lines as that shown, described and claimed in our contemporaneouslypending application filed February 21, 1914, Serial No. 820,351. `Said fastener involves parts 1 in its Ineke-up a body portion as 2, and a clamping portion as`3,th e body portion being practically of bowed form and the' i clamping portion 3 consisting of a flange extending inwardly from one terminal of the body portion 2 at approximately an acute angle thereto. In the present instance the body portion and flange are integral. As a matter of factwe prefer that the device be made inone piece from sheet metal, the blank shown in Fig. 9 and hereinafter more particularly described in detail answering satisfactorily in this connection. Approximately midway of the length of the body 2 is a rope-receiving opening and the circular `hole or perforation 4 meets our frequirements. The hole 4 `is nearer the front edge of the body portion 2 than the rear so as 'to facilitate the proper looped connection In addition to the opening 4f there is a secondand larger opening, 5, also shown as circular and formed jointly in the body 2 and `clamping flange 3, the hinge ,of exure line at the juncture of i the body portion 2 and the clamping portion 3 radially intersecting the circular hole approximately centrally thereof. From this' it will "be clear that the clamping portion 3 is capable offswingilng motion. y The inwardly extending flange 3 is provided in turn with a flange fi at right an# gles thereto and which e-xtends toward the interior Iof the body 2. The flanged part of the clamping portion 3 is spaced or separated from the adjacent terminal of the body portion 2a distance suliicient to provide for the passage of the cord 7, although one portion of the space between said particular terminal' and the flange 6 is narrowed for a purpose that will be hereinafter explained. The flange 6 has teeth 9, 10, 11 and 12, the space between the teeth 11 and 12 being greater than that between the teeth 9 and 10L and 10 and 11, which two last-mentioned spaces approximately equal the space between the teeth 11 and 12, 'being intended to provide for the ready movement of the free end of the cord into the fastener by way of the opening 4. The nonflanged end of the body portion 2 has its inner portion bent or deflected toward the flange 6 as at 13, this end of the space between the non-flanged end of the body 2 and flange 6 being narrower than the remainder and such narrowed portion being adapted to insure an initial hold upon the extreme free endl of the cord 7. i

In `use the cord is first passed through the hole 4, the diameter of which exceeds that of the cord. The cord is then passed through the space between the teeth 11 and 12 and is then brought over the outside of the flange 3 and extended across said flange toward the inner side of the fastener in a diagonal direction, being passed. through the large hole 5. It is drawnthrough said larger hole and its free end is squeezed into the narrow space -between the deflected portion 13 and flange 6. It will be noted that there is now a loop Yconnected with the fastener and that a part of this loop embraces the flange 3. It follows, therefore, that when the cord 7 is pulled in the direction of the arrow (Fig. 7 the clamping and loop-receiving portion 8 is caused to swing inward around its axis at the junction of said clamping portion with the body 2, so that the clamping portion through its flange 6 is'caused to bite into the looped part of the cord, the inner portion or practically half of the flange 6 equipped with the teeth 9, and 10 and 11, entering the cord at right angles thereto so as to secure the irmest possible purchase upon the cord near its free end. The other part of the Hange 6 engages through its teeth 11 and 12, the outer portion of the loop. The consequence is that the greater the pull on the cord 7, the greater will be the hold of the fastener on the cord.

eferring now to Fig. 1. The numeral 14 denotes a sash, 15, a sash weight and 16 a guide pulley. The sash 14 has a counterbore 17 to receive a fastener, the cord-receiving channel 18 extending upwardly from and intersecting the counterbore. We will hereinafter describe briefly how the parts are mounted. lhen the fastener is employed in connection with a sash of wood or other material we provide means of a positive nature for holding the fastener in place and one or more teeth adapted to penetrate the wood answer satisfactorily in this connection. The body portion 2 is notched as at 19 in the inner edge thereof substantially centrally of said edge and from the end walls of the slot or notch 19, the bevel teeth 2O project. The inner sides of these teeth as shown are at right angles to the body portion 2, although this may not be necessary iu all cases, while the outer sides are beveled, the beveling being in a direction away from the inner edge of the body portion 2, the result being that the teeth are pointed or sharpened. By beveling the teeth on their outer sides, the fastener can be more readily inserted in the counterbore 17. When the oord 7 is pulled that fastener which is in the counterbore 17 will be operated on by the cord so as to cause the bevel teeth or prongs 20 to penetrate the wood of the sash and thereby securely hold thefastener in place in the counterbore 17.

In using the fastener in connection with a window, the following procedure may be adopted: `The cord 7 is threaded through a, fastener in the manner already described after which the fastener is mounted in the counterbore 17. The cord is then laid in the groove 18 and passed upwardly over and then down from the guide pulley 16. On pulling the cord 7 the fastener is set and locked in position in the manner already described. The opposite end of the cord is then passed through the eye 21 in the sash weight 15 and a fastener connected with it. By pulling on the outer portion of the cord 7 the second fastener will be set.

In Fig. 9 is shown a blank from which the article can be made. This blank is denoted in a general way by 22, having holes 4 and `5 and the inner edge slot or notch 19 and the end teeth 9, 10. 11 and 12. From this flat blank the article can be shaped up in steps 1n any desired order and at a suitable stage in the process the walls of the notch or slot 19 can be cut from the remainder of the blank and bent outward to make the teeth 20.
